How much are souveniers in Paris?
I am going to Paris in a week and I want to know how much money I need to bring.
Cost for keychains?
T-Shirts?
Little Eiffel Tower Statues?
Magnets?
It depends where you go. The two best areas I’ve discovered for souvenir shopping are near the Louvre on Rue de Rivoli and near Notre-Dame Cathedral. The further away from a major tourist attraction you go, the less expensive the souvenirs.
I’ve seen mini Eiffel Towers for 1 Euro each. Magnets can be up to 6 Euros, depending on how elaborate the design is. T-shirts can range from 10 to 25 Euros. Keychains are approximately the same price as magnets.
